To My Readers



If this is the first time you're visiting my blog, thank you. Whether you're interested or just curious to find out about PCB reverse engineering (PCB-RE), I hope you'll find something useful here.

This blog contains many snippets of the content in my books to provide a more detailed overall sampling for my would-be readers to be better informed before making the purchase. Of course, the book contains more photos and nice illustrations, as evidence from its cover page. Hopefully, this online trailer version will whet your appetite enough to want to get a copy for yourself.

Top Review

I started doing component level repair of electronics with (and without) schematics more than 40 years ago, which activity often involves reverse-engineering of printed circuit boards. Although over the years my technical interests have shifted into particle beam instrumentation, electron microscopy, and focused ion beam technology fields, till this day——and more often than not——PCB repairs have returned multiple multi-million-dollar accelerators, FIB, and SEM instruments back to operation, delivering great satisfaction and some profit.

Many of the methods described by Keng Tiong in great details are similar to the approaches I've developed, but some of the techniques are different, and as effective and useful as efficient and practical. Systematic approach and collection of useful information presented in his books are not only invaluable for a novice approaching PCB-level reverse engineering, but also very interesting reading and hands-on reference for professionals.

Focus on reverse engineering instead of original design provides unique perspective into workings of electronics, and in my opinion books by Keng Tiong (I've got all three of them) are must-read for anybody trying to develop good understanding of electronics——together with writings by Paul Horowitz and Winfield Hill, Phil Hobbs, Jim Williams, Bob Pease, Howard Johnson and Martin Graham, Sam Goldwasser, and other world's top electronics experts.

A Word of Thanks

Thanksgiving is a special season. It brings to mind the wonderful people we meet and the beautiful times and memories we had throughout the year. And as we gather with family and friends over a sumptuous feast, we can't help but be thankful, that despite the pandemic that has ravaged for the past two years, two things still remain close and precious to our hearts——family and friendships.

While Thanksgiving Day is not a national holiday in my country, I want to take this opportunity to thank all my readers——those who have supported my works and left glowing reviews to spur me on in this journey which I started six years ago. Your honest purchase of my books has made it possible for me to continue writing and giving to charities, however meager by comparison to other renown authors. Still, it's the thought that counts, isn't it?

It is my hope that the knowledge and experience I put into print will benefit the electronics community for many years to come. As each generation of engineers embark on this challenging yet rewarding adventure of doing PCB-RE, may they hear the faint echo of this obscure writer cheering them onwards to master this niche and coveted skillset, long after he is gone.

Happy Thanksgiving Day, my readers! Stay safe and well throughout this festive seasons...
